Description
Technical Field
The utility model relates to a linear guide technical field, in particular to dustproof linear guide of bottom surface installation.
Background
Linear guides can be divided into three types: the roller linear guide rail, the cylindrical linear guide rail and the ball linear guide rail. The linear motion device is used for supporting and guiding a motion part to do reciprocating linear motion in a given direction, can bear certain torque, and can realize high-precision linear motion under the condition of high load.
The technology of linear guides is particularly widespread, for example: precision metrology instruments, CNC machines, robotic arms, medical equipment, construction equipment, automation equipment, and the like. The linear guide rail is widely applied to linear motion bodies on automation equipment, construction equipment and precision machinery. General linear guide has dustproof performance poor because structural design, manufacturing reason, especially brings the dust or the pollutant on the guide rail into the guide rail easily in the motion process, easily causes whole linear guide use accuracy to reduce the problem that skill life shortens to influence the operation accuracy and the life of whole board equipment.
Therefore, it is desirable to provide a linear guide rail with good dustproof effect.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a bottom surface installation dustproof linear guide rail, which can effectively solve the technical problems that the linear guide rail is easy to bring dust or pollutants on the guide rail into the guide rail in the linear motion process, so that the use precision of the whole linear guide rail is reduced and the service life of the whole linear guide rail is shortened, thereby influencing the operation precision and the service life of the whole machine station equipment; a linear guide rail which can be operated in a highly dust-polluted environment such as a woodworking machine and a CNC working machine, etc. is provided.
For realizing the purpose of the utility model, the utility model discloses a technical scheme include:
the utility model provides a bottom surface installation linear guide that prevents dust, includes guide rail, slider and dustproof mechanism, have last ball chain and ball chain down in the slider, the guide rail top surface does not have the mounting hole, dustproof structure is guide rail bottom surface blind hole installation screw hole, the effective length of guide rail bottom surface blind hole installation screw hole is 3/5-4/5 of guide rail height.
Further, the installation threaded holes of the blind holes on the bottom surface of the guide rail are selected to have the spacing of 60mm/80mm/105mm according to different models.
Compared with the prior art, the utility model has the advantages that: the top surface of the guide rail is not provided with a mounting hole, the mounting threaded hole is positioned on the bottom surface of the guide rail, and the guide rail is mounted from the bottom surface when being mounted, so that the technical problems that the use precision of the whole linear guide rail is reduced and the service life of the whole machine equipment is shortened due to the fact that dust or pollutants on the guide rail are easily brought into the guide rail in the linear motion process of the linear guide rail, and the operation precision and the service life of the whole machine equipment are influenced can be effectively solved; the utility model provides a pair of dustproof linear guide of bottom surface installation can utilize the machine equipment of work in the high polluted environment of high dust, like wood working machine and CNC processing machine etc..

FIG. 2 is a schematic view of a bottom-mounted dustproof linear guide structure provided in an embodiment of the present invention
In the drawings: 1. a guide rail; 2. a slider; 3. a ball rolling chain is arranged; 4. a ball rolling chain is arranged; 5. and a dustproof structure.
Detailed Description
In view of the deficiencies in the prior art, the technical solution of the present invention can be provided through long-term research and a large amount of practice. The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention.
Fig. 1 is a sectional view of a bottom-mounted dustproof linear guide rail structure provided in an embodiment of the present invention; fig. 2 is a schematic structural view of a bottom-surface-mounted dustproof linear guide rail provided in an embodiment of the present invention. As shown in fig. 1 and fig. 2, the dustproof linear guide provided in the embodiment of the present invention includes: the dustproof structure comprises a guide rail 1, a sliding block 2 and a dustproof structure 5, wherein an upper rolling ball chain 3 and a lower rolling ball chain 4 are arranged in the sliding block 2, and the top surface of the guide rail is not provided with a mounting hole; the dustproof structure 5 is a blind hole installation threaded hole in the bottom surface of the guide rail, and the effective length of the blind hole threaded hole with the standard interval in the bottom surface of the guide rail is 3/5-4/5 of the height of the guide rail 1.
The utility model discloses the dustproof linear guide of bottom surface installation that provides in the example, guide rail bottom surface blind hole installation screw hole selects 60mm 80mm 105 mm's interval according to the difference of model.
To sum up, the utility model provides a bottom surface installation dustproof linear guide, adopts the design that the guide rail top surface does not have the mounting hole, and the mounting screw hole is located the guide rail bottom surface, installs from the bottom surface when the guide rail is installed, and it can effectively solve the linear guide in the linear motion process, easily brings the dust or pollutant on the guide rail into the guide rail, causes the whole linear guide to use the precision reduction and the life shortens to influence the operation precision and the technical problem of life of whole board equipment; the utility model provides a pair of dustproof linear guide of bottom surface installation can utilize the machine equipment of work in the high polluted environment of high dust, like wood working machine and CNC processing machine etc..
